Last reviewed October 19, 2026

In plain words: Enriched wheat flour is wheat flour that meets the US flour standard and has added B vitamins (thiamin, riboflavin, niacin, folic acid) and iron.

What the evidence review says

Enriched wheat flour is white flour with added B vitamins and iron, as required by the US flour standard. The added vitamins are a public-health measure, not a contaminant; folic-acid fortification was followed by fewer neural-tube-defect births in the US. Wheat contains gluten and is a major allergen, which matters for people with celiac disease or wheat allergy.

The enrichment vitamins are a public-health measure, not a contaminant. Wheat flour contains gluten and is a major allergen, which matters for people with celiac disease or wheat allergy. Folic-acid fortification of enriched grains was followed by fewer neural-tube-defect births in the United States. The upper level for synthetic folic acid concerns high doses, mainly masking of vitamin B12 deficiency, and the flour standard is a fortification level rather than a supplement dose. Potassium bromate is not required by the enriched-flour standard.
